ParamOrbitRV

class ssapy.rvsampler.ParamOrbitRV(*args, **kwargs)

Bases: ParamOrbitTranslator

A class for translating orbital parameters in position-velocity (RV) form, including conversions between parameters and orbit objects.

Inherits:

ParamOrbitTranslator : Base class providing foundational functionality for orbital parameter translation.

Methods:

__init__(*args, **kwargs):

Initialize the ParamOrbitRV object, inheriting behavior from the ParamOrbitTranslator base class.

param_to_orbit(p):

Convert position-velocity (RV) parameters to an Orbit object.

parray-like

Orbital parameters in position-velocity form. The first three elements represent the position vector (r), and the next three elements represent the velocity vector (v).

Orbit

An Orbit object created from the position (r) and velocity (v) vectors, along with propagation keywords.

• Additional propagation keywords are extracted from the full parameter set.

• The Orbit class is expected to support initialization with r and v.

orbit_to_param(orbit):

Convert an Orbit object to a list of position-velocity (RV) parameters and associated propagation keywords.

orbitOrbit

An Orbit object containing position (r) and velocity (v) vectors.

numpy.ndarray

A concatenated array of position (r), velocity (v), and propagation keywords extracted from the orbit.

Notes:

• This class assumes orbital parameters are represented in position-velocity form.

• The Orbit class is expected to provide attributes r and v for position and velocity vectors, respectively.

Example:

>>> translator = ParamOrbitRV()
>>> params = [7000, 0, 0, 0, 7.5, 0]  # Example position-velocity parameters
>>> orbit = translator.param_to_orbit(params)
>>> new_params = translator.orbit_to_param(orbit)
>>> print(new_params)
[7000, 0, 0, 0, 7.5, 0]  # Example output matching input
